actually she's been practicing in tallinn for the last few weeks. saw both her coaches at tere today, kaia must have practiced indoors due to rain and stormy weather. she surely had courts booked twice a day at rocca last week. so she does not appear to be injured unless smth dramatic happened very recently.
I guess they want to be very careful with playing on hard surface as there are also Tokyo, Beijing etc. coming up soon enough. So she is betting on these big tournaments only. As long as she can make a deep run on some of them, then why not.
